City Nature Challenge 2019

Help Houston Win the City Nature Challenge (, April 26 – April 29!

Cities around the world will be competing to see who can make the most observations of nature, find the most species, and engage the most people in the 2019 City Nature Challenge.

To participate is quite easy:

  • Open a free account on iNaturalist
  • Take photos or record sound (e.g. birds, frogs) of living organisms; record location of this observation. Observations must be made and posted between April 26 – April 29.
  • Post your observations on iNaturalist. Either take the photo with location feature on or enter the location manually later on the computer.
  • You do not need to ID your observations.
